Summary


The Mercedes-Benz GLB is a mid-sized SUV available with either five or seven seats. It is based on the smaller GLA model, although it is closer in size to the larger GLC. The GLB arrived in the UK in late 2019.

The GLB is currently available with either a petrol or diesel engine, although a plug-in hybrid is likely to join the range at a later date. There is also a high-performance model called the Mercedes-AMG GLB 35 – we are building a separate page for this model, so be sure to check back soon.

It has received praise from reviewers for its comfort, safety and advanced technology; however it has been criticised for limited practicality compared to similarly-priced rivals, and for only offering a limited choice of engines.

As of January 2024, the Mercedes-Benz GLB holds an Expert Rating of B, with a score of 67% on our unique Expert Rating index.

Running costs for the Mercedes-Benz GLB range are a mixed bag, according to data provided exclusively to The Car Expert by our commercial partner, Clear Vehicle Data.

Fuel economy is disappointing for petrol models and around the market average for diesel-engined versions. Compared to the rest of the mid-sized SUV sector, the car’s service and maintenance costs are pretty average. Insurance costs likely to be around the market average too, though, based on data from the UK’s insurance group assessor, Thatcham Research.
